We leverage U.S. county-day temperature variation combined with daily time use data to examine the effect of temperature on the timing of work. We find that warmer (colder) temperatures increase (decrease) working time during the night and decrease (increase) working time in the morning. These...

We propose a twin family model linking twins with their spouses and children to quantify the relative importance of genetic and environmental factors in explaining the variance of socio-economic outcomes. Using data from the Danish Twins Registry and population registers, we test and relax the...

We leverage U.S. county-day temperature variation combined with daily time use data to examine the effect of temperature on the timing of work. We find that warmer (colder) temperatures increase (decrease) working time during the night and decrease (increase) working time in the morning. These...

This paper examines the impact of increasing the relative cost of fixed-term contracts on labor demand as well as the demand for standard measures of human capital and specific skill requirements. We evaluate a 2018 Italian labor law reform that raised the cost of fixed- term contracts while...

Correlations between the earnings of siblings reflect shared family and community background, but evidence is mixed on the relative magnitudes of these influences. We estimate long run earnings correlations between brothers, school mates and teenage neighbors jointly in a unified framework....

Using longitudinal data based on administrative registers for the population of Danish men we develop a model which accounts for the joint earnings dynamics of siblings and youth community peers. We are the first to decompose the sibling correlation of permanent earnings into family and...

Job protection reduces job turnover by changing firms' hiring and firing decisions. Yet the effect of job protection on workers' quit decisions and post-quit outcomes is still unknown. We present the first evidence using individual panel data from 12 European countries, which differ both in...

Social interactions have important consequences for labour market outcomes. Yet the growing literature has relied on indirect definitions of networks. We present the first evidence based on direct information on friends' networks. We address issues of correlated effects with instrumental...

With the emergence of the Great Recession unemployment insurance (UI) is once again at the heart of the policy debate. In this paper, we review the recent theoretical and empirical evidence on the labor market effects of UI design. We also discuss policy issues related to UI design, including...

This paper studies the influence of family, schools and neighborhoods on life-cycle earnings inequality. We develop an earnings dynamics model linking brothers, schoolmates and teenage parish neighbors using population register data for Denmark. We exploit differences in the timing of family...
